OCB Scoping Workshop: Improving predictive biogeochemical models through single cell-based analyses of marine plankton physiological plasticity, genetic diversity and evolutionary processes

Bigelow Laboratory for Ocean Sciences, May 28-30, 2014

The global ocean is currently undergoing significant changes, from the acidification of surface seawater to expansion of mid-water oxygen minimum zones to changes in vertical stratification and nutrient inputs.  Understanding these present changes and prediction of their impact on marine plankton-driven biogeochemical processes requires detailed information at the level of the individual organism, such as their physiological traits, characteristics, rate processes and plasticity to respond to environmental change.  Recent progress in various single cell and population-level analytical techniques offers an opportunity to bridge this knowledge gap.

This scoping workshop brought together scientists with complementary interests in observing and/or modeling specific traits and physiological characteristics and rates in marine plankton. The objectives of the workshop were to summarize our current state of knowledge of physiological observations in single cells and taxonomic populations from the environment, identify impediments to filling this knowledge gap (including data handling and analysis), and discuss future research areas. The workshop provided opportunities for the ocean science community to formulate a forward-looking vision on future research directions regarding the roles of genetic diversity, physiological plasticity and evolutionary processes in marine biogeochemical cycles.
